As shown in fig. 1, an intraoral scan bar 100 according to an embodiment of the present invention includes a scan component 1 and a connecting component 2 connected to the scan component 1. The scanner unit 1 has a scanner mark portion. The intraoral scan rod 100 is connected to the implant by a connecting member 2. Wherein, the scanning component 1 is made of plastic material, and the hardness of the material of the connecting component 2 is larger than that of the plastic material.
Wherein, compared with the prior art, the hardness of the connecting part 2 of the intraoral scanning rod 100 is improved, thereby increasing the wear resistance of the connecting part 2 of the intraoral scanning rod 100 and prolonging the service life of the connecting part 2 and the whole intraoral scanning rod 100.
In a specific application example, the connecting member 2 may be made of a titanium alloy material. The titanium alloy material has high wear resistance and is not easy to wear.
Further, as shown in fig. 1 to 4, one end of the scanning unit 1 may have a slot 101. The connecting part 2 has an insertion section 23. The insertion section 23 is inserted into the insertion groove 101 and remains fixed relative to the scanning unit 1.
In the above example, the connecting part 2 and the scanning part 1 are fixed in a plugging manner, which has the technical effect of convenient assembly.
As shown in fig. 1 to 4, one of the inner wall of the insertion groove 101 and the outer wall of the insertion section 23 may be provided with a groove 13, and the other may be provided with a convex hull 22. The convex hulls 22 are intended to snap into the grooves 13 so that both the insertion section 23 and the scanning unit 1 remain relatively fixed.
In the above example, the convex hull 22 and the concave groove 13 are in snap fit, so that the connection stability of the connecting component 2 and the scanning component 1 can be further improved, and the two components can be prevented from being loosened.
Further, both the convex hull 22 and the groove 13 may be annular, so that both the connecting component 2 and the scanning component 1 are clamped in the circumferential direction, and the connection stability of the two is further improved.
Furthermore, as shown in fig. 1 to 3, the outer wall of the connecting part 2 may have a limiting boss 21, the limiting boss 21 is used to abut against one end of the scanning part 1 to limit the depth of the insertion section 23 inserted into the insertion groove 101, so as to facilitate the assembly of the connecting part 2 and the scanning part 1, after the insertion section 23 is inserted into the insertion groove 101, when one end of the scanning part 1 abuts against the limiting boss 21, that is, the insertion section 23 is inserted in place, thereby improving the insertion accuracy of the insertion section 23.
Further, as shown in fig. 1, 3 and 4, the bottom of the insertion groove 101 may have a first screw through hole 102 therethrough. The end of the connecting part 2 opposite the insertion section 23 has a connecting section. The connecting section is used for being connected with the implant. The connection part 2 also has a second screw through hole 201 penetrating from the end of the insertion section 23 to the end of the connection section. The second screw via hole 201 is opposite to the first screw via hole 102. The second screw via hole 201 has a countersunk groove 202 therein.
As shown in fig. 5, the intraoral scan rod 100 of the present invention further includes a screw 3. The screw 3 may pass through the second screw passing hole 201 via the first screw passing hole 102 and be threadedly coupled with the implant to fix the coupling member 2 to the implant. And because the connecting part 2 and the scanning part 1 are fixed relatively, the whole scanning rod is fixed on the implant.
As shown in fig. 2, the aforementioned connecting section may have a hexagonal prism shape to match with the internal hexagonal prism groove of the implant, so as to prevent the connecting part 2 from rotating relative to the implant, and improve the connection stability of the intraoral scan rod 100 and the implant.
Further, the aforementioned scan identification part may include a first scan identification part and a second scan identification part. The first scan marker is located on a first side of the scan component 1. The second scanning mark is located on a second side of the scanning component 1. The first side part and the second side part are back.
In the above example, the scan marks are provided on both sides of the scan component 1 opposite to each other, which facilitates positioning during scanning.
Further, as shown in fig. 1 and 4, the first scanning mark part may be a first groove 11, and the second scanning mark part may be a second groove 12. The first groove 11 and the second groove 12 both extend from the end of the scanning component 1 away from the connecting component 2 to the end of the scanning component 1 close to the connecting component 2, and the extension lengths of the two grooves are not equal. Therefore, when the doctor places the intraoral scanning rod 100, the direction can be conveniently identified, and the intraoral scanning rod can not be reversely placed, so that the assembly is convenient, and the assembly efficiency is improved.
Here, it should be noted that: in the case of no conflict, a person skilled in the art may combine the related technical features in the above examples according to actual situations to achieve corresponding technical effects, and details of various combining situations are not described herein.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
